Sandbox

For playing around during development.

Todo:

check that lookup table data is bound to the instance, not to the class

PySD Performance

Lets plot the history of our speedup efforts:



In [13]:

    
import pandas as pd

dictlist = []
with open('tests/speedtest_results.json') as infile:
    for line in infile:
        dictlist.append(eval(line))
    
speedtests = pd.DataFrame(dictlist)
speedtests['run teacup baseline'].plot(marker='o');
